Added a line in our config file for setting the block ID of Corium. Even
though it's only temporary code that's going to be removed later, people
need that to run our dev builds properly.
Changed Rift Blade recipe to use Stable Fabric and a Blaze Rod. Changed
its base material from Gold to Diamond, which increases attack power and
decreases enchantability a little.
1. Made World Thread available as dungeon loot
2. Removed useless config options for loot that doesn't appear anymore
3. Tweaked some config names and variable names for consistency
